Abstract (en)

[origin: EP3370376A1] The present invention discloses a data transmission acceleration method and a related apparatus and system. The method includes: sending, by a sending node, data packets to a receiving node at a specific rate, where each data packet carries a random sequence number and a scrolling sequence number related to a packet sending sequence; and quickly determining, by the receiving node, a lost data packet according to double sequence numbers of a received data packet, and feeding back sequence number information of the lost data packet to the sending node, so as to instruct the sending node to retransmit the lost data packet. The solutions of the present invention can improve a network throughput rate/transmission rate in a network with a high delay and a high packet loss rate, and the high throughput rate/transmission rate does not dramatically change because of some network jitter.
